In a world where things drift away in a blink, McDonald’s ‘Big Mac’ remains a hallmark of comfort foods. It’s probably the one thing that pops up in your head when you hear the words, “fast food.”

Even in its 50th year, generations after generations still have an appetite for the burger, which has played witness to the creations and extinctions of innovations and trends. The brand has inventively marked this milestone with a t-shirt collection that doubles as discount tickets, a watch, and a Coca-Cola can—testaments to how the menu item has become a pop culture icon.

McDonald’s creative agency,TBWA, has consolidated 50 striking posters made by talents from its offices around the world that pay homage to the ‘Big Mac’ and illustrate the things that have come and gone since its introduction.

Led by TBWA\Chiat\Day NY and TBWA\Zurich, the project sees creations made using a diverse range of techniques spanning from paper craft, illustration and embroidery, to CGI, physical prop design, and screen printing. Out of the 50, 10 were designed by famed graphic artist Alex Trochut.

In this length of half a decade, jukeboxes have become Spotify, Bitcoins are set to replace cash, tools are apps, the primary way of talking is through messaging clients, but the ‘Big Mac’ is still a ‘Big Mac’.

What else has changed? Take a look at 15 posters from the collection, which is now live in Switzerland and will roll out via several other channels and formats throughout the year.
